The 38-year-old East Orange woman had pleaded guilty in September to reckless manslaughter, shortly before her trial was to start. She admitted delivering the silicone injection that killed Justin Street in 2011.

Authorities say the 22-year-old East Orange man went to Rivera’s home so she could inject his penis with silicone, which he hoped would enlarge it. But the silicone she used wasn’t the kind used for medical procedures, and it caused an embolism which killed him.

Rivera acknowledged that she wasn’t a trained doctor or licensed to administer the injection.
